DISPATCH INSTRUCTIONS

- WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED:

Product knowledge, MaxRep3

TIME ESTIMATE: 45 minutes

TASK COMPLEXITY: 0

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW:

What: A cooling fan in a MaxRep3 Engine has failed and needs to be replaced.

Where: There are two types of fans in the MaxRep3 Engine, each of the two power supplies contains a fan as well as there being five fan modules for the system board.

Fan 0 = power supply 0*
Fan 1 = power supply 1*
Fan 2,3 = fan module 0 (left most)
Fan 4,5 = fan module 1 (left center)
Fan 6,7 = fan module 2 (center)
Fan 8,9 = fan module 3 (right center)
Fan 10,11 = fan module 4 (right most)

* Fan replacement for MaxRep3 Engine power supplies are  covered in <Document ID 2065405.1>.

Why: A system board cooling fan has failed.

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?

The MaxRep3 Engine with the fan problem will have a Warning status in the Oracle FS System Manager GUI.  This procedure requires the MaxRep3 Engine to be offline.

QRC for this procedure:

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE:

1. Disable Call-Home to prevent spurious alerts (see <Document 1942676.1> FS System: How to disable Call Home to prevent Automatic Service Request ASR Generation).
2. Use ESD precautions.
3. Shutdown the MaxRep3 Engine (see <Document 2066803.1> MaxRep: How to Perform a Graceful Shutdown of the Oracle MaxRep3 Engine).
4. Remove failed fan:
1. Deploy the anti-tip legs in the front of the rack.
2. Slide the MaxRep3 Engine into the service position.
3. Unplug both power cords.
4. Loosen the two captive screws in the rear of the top cover.
5. Slide the top cover back and remove.
6. Grasp the strap-handle of the failed cooling fan and tug upwards to remove.
5. Install replacement fan:
1. Install the replacement cooling fan into the vacated slot.
2. Close the top cover being certain to catch the mushroom tabs in the front to secure it.  Failure to do so will inhibit the MaxRep3 Engine being slid back into the rack.
3. Tighten the two screws in the rear.
4. Plug in both power cords.
5. Return the MaxRep3 Engine to the rack position.
6. Return the anti-tip legs to their normal position.
6. After 4-5 minutes, the MaxRep3 Engine should have completed it's boot sequence - Access the User Interface and resync any Protection Plans that require it (see <Document 2066803.1> MaxRep: How to Perform a Graceful Shutdown of the Oracle MaxRep3 Engine).
7. When finished, re-enable Call-Home.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Confirm that the replacement Cooling Fan was successful - the Warning under Status Summary in the Oracle FS System Manager GUI associated with it should be gone and the FS1-2 should be normal/green.
